Mars Global Polyhydrated Sulfate (MGS-1S) Martian Regolith Simulant

What Mars Global Polyhydrated Sulfate Simulant MGS-1S is A sulfate-enhanced Mars regolith simulant derived from MGS-1 designed for in-situ resource utilization (ISRU), chemical reactivity, and hydration process studies under Martian analog conditions. What This Simulant Represents MGS-1S is a sulfate-focused derivative of the Mars Global Simulant (MGS-1). It emphasizes the sulfate-rich mineral behavior observed in specific Martian terrains (e.g., Meridiani Planum and other sulfate-bearing regions), where hydrated sulfates such as gypsum and kieserite have been identified. This simulant retains the general Martian soil analog characteristics of MGS-1 — including a particle size distribution <1 mm — while introducing sulfate-like phases to support experiments where sulfate chemistry and hydration reactions are central to process understanding. MGS-1S enables controlled laboratory studies of sulfate-related reactions to fluids, thermal cycling, and chemical extraction workflows that ar
